> Because it seems fair enough as en engineering decision? Huh? Supporting hardware with drivers is purely a software decision, its not as though software adds noteworthy weight to a device. > Apple also provide firmware updates far longer than most manufacturers Only for iPhones, on Mac they leave your iCloud email in in plaintext on the UEFI after the computer is wiped. For computers, expect 6 to 7 years of macOS updates at most, meanwhile Windows & Linux offer support to ancient i386 systems still.

    Because a failure that causes one interface to fail, but not the other seems really unlikely. Plus it wouldn't just be another driver to write, you also have to come up with some logic that determines if one has failed and use the other instead. This isn't linux where you can reasonably tell users "oh just blacklist this kernel driver and it'll use the other instead."

Its a fairly common water damage issue for Macbooks where the SPI bus will be damaged, but the USB connection will be fine. > come up with some logic that determines if one has failed and use the other instead. Once again, go follow that link. Apple already built the logic, just instead of switching to USB, it begs you to pair a bluetooth keyboard!

        Ah, sorry, I wasn't somewhere I could watch the video. If that's the case, I take back what I said, it could probably make sense to include both drivers then.

        No worries, I avoid linked videos like the plague myself. This one is decently short (for these types of repair videos) at 11 minutes, and is pretty easy to jump through if your pressed for time.

How much of your email are they storing in UEFI? And why?
- StudentStuff 9y ago
  The full email address is stored, there are a couple videos where Louis Rossman nabs the email address (occasionally with an SPI programmer) and contacts the original owner, finds out the laptop is stolen and returns it.
  - mattl 9y ago
    Oh the email address. That makes more sense. I thought perhaps they were storing iCloud email in the chip for your account.

This is not really true, the difference is much smaller and you will not boot windows 10 with the i386 feature set. Since Windows 8 the NX bit is required, making it require relatively modern CPU's, mostly x86_64, allthough a few x86 has it as well. So for example, you can run the 32bit version of win 10 on the 32bit Core Duo (it has nx), while OSX with its 64bit requirement needs a Core 2 Duo. Newer OSX require a graphics card of DX10 level, Windows 10 require DX9 level.

It's fairly easy to wipe it with one of these commands/procedures: - sudo nvram -d fmm-mobileme-token-FMM - sudo nvram -c # this one will wipe the entire NVRAM, use with care! - https://support.apple.com/en-us/HT204063 > For computers, expect 6 to 7 years of macOS updates at most High Sierra can be installed on "Late 2009 iMacs", that right there is 8 years of security and feature updates. Those models will get security and point updates, at the very least, until the next version of macOS, for a total of 9 years (if not more, we'll see).

  Last year's macOS Sierra won't install on my wife's 2010 Macbook Pro. Apple doesn't seem to always roll off support every year. I'm guessing some version adds new tech and they drop support for 3-4 years worth of hardware all at once (that hardware is usually at minimum 5 years old).
